CLTI- & CLXI-2IND/4IND
Functional Summary
The CLTI/CLXI-2IND is a 2-inductor terminal block and
module kit while the CLTI/CLXI-4IND is a 4-inductor
terminal block and module kit. Inductor modules are
typically used to reduce hum from incandescent lamps
that are connected to dimmer modules in a Crestron
lighting system. These kits can be mounted in any
Crestron Automation Enclosure (CAEN or CAENIBSeries Enclosures). The terminal block is for connecting
wires into and out of the inductor module. The inductor is
wired in series between the output of the dimmer module
and the load. The maximum load for any inductor in the
module is 10 amps.
Each of these Terminal Block and Module kits is
considered single entities and must be used together. The
terminal blocks (CLTI-2IND and/or CLTI-4IND) are
shipped separately from their respective modules
(CLXI-2IND and CLXI-4IND) to permit termination of
the field wiring to the terminal block prior to installation
of the module, as described in this guide.
CLXI-2IND and CLXI-4IND modules can also be
connected to CLTIBN-2IND and CLTIBN-4IND terminal
blocks. For installation information, refer to the latest
version of the CLTIBN Installation Guide (Doc. 6561)
which is available for download from the Crestron
website (www.crestron.com/manuals).
Installation
The terminal block and module must be mounted into a
Crestron Automation Enclosure by a licensed electrician,
in accordance with all national and local codes.
NOTE: Inductor modules and terminal blocks should be
installed above the dimmer modules, towards the top of
the CAEN or CAENIB enclosure.

CAUTION: This equipment is for indoor use only.
Mount in a well-ventilated area. The ambient temperature
must be 0°C to 40°C (32°F to 104°F). The relative
humidity must be 10% to 90% (non-condensing).
Terminal blocks are installed along the left side of singlewide enclosures and along the outside edges (left and
right sides) of double-wide enclosures. Modules are
installed along the right side of single-wide enclosures
and side-by-side in the center of double-wide enclosures.
When installing modules and terminal blocks in a double-

that they can be properly wired. Refer to the illustrations
shown in the next column when considering the location
of terminal blocks and modules within an enclosure.

Installation and Field Wiring
NOTE: If CLTIBN terminal blocks are to be used, refer
to the latest version of the CLTIBN Installation Guide
(Doc. 6561).
NOTE: Both left-side and right-side adhesive wiring
labels are provided. The left-side labels are used in both
single and double-wide enclosures. The right-side labels
are only used in double-wide enclosures.
1. Remove the backing from the left or right
adhesive wiring label.
2. Apply the adhesive label by aligning the holes in
the label with the holes on the Crestron
Automation Enclosure where the terminal block
is to be mounted. The wiring label lies beneath
the terminal block as shown in the two wiring
diagrams on this page.
3. Use the two supplied self-tapping pan Phillips
screws (8B x ¼ length (6mm)) to secure the
terminal block to the Crestron Automation
Enclosure.
CAUTION: Bypass jumpers are provided to allow
testing of circuits and to protect the module during
installation. When properly secured by two screws,
each of the two jumpers on terminal block shorts the
dimmer output to the load so that the circuit is
energized. Do not remove any bypass jumpers until
all dimmer and load wiring has been completed, the
circuit has been tested for electrical faults, and the
module has been installed. Refer to “Module
Installation” on next page.

4. With the circuit breaker turned off, connect the
dimmer module output (IN) and the load (OUT)
wires to the IND terminal block per the markings
provided on the wiring label (as shown in the
following diagrams). Terminal blocks accept one

does not trip and that the proper lighting loads
are energized.

Module Installation
NOTE: Modules are to be installed after enclosure
has been completely wired. Refer to the terminal
block installation procedure on page 2 for details.
1. Use the four supplied self-tapping screws (8B x
¼ length (6 mm)) to secure the module to the
enclosure.
2. As shown in the following wiring diagrams,
connect the wires from the module to the
terminal block. Wires are pre-stripped to 12 mm.
Tighten to 1 Nm.
NOTE: Each inductor should be wired with one
wire connected to an input and the other wire
connected to the corresponding output. The inductors
have no polarity.
3. Turn off the circuit breaker and remove the
bypass jumpers on the terminal block. Refer to
following diagrams for a close-up of the
jumpers.
